A fundamental problem in getting to grips with the ocular blood flow literature is the difficulty in comparing the results of similar studies employing different assessment techniques. As evident from the discussion above, each technique evaluates a portion of the ocular circulation in a distinct way. Some of the methods overlap with regard to the tissues that can be used for examination, while others are directed at entirely different parts of the ocular vasculature. Despite these difficulties, hemodynamic studies of glaucoma and AMD are likely to grow in importance. On the basis of accumulating epidemiological and clinical evidence, it is becoming apparent that intraocular pressure is not the sole etiological factor in glaucoma, and retinal pigment epithelium senescence is not the sole etiolog...

It is painful, may progress to inflammation of the uveal tract, and in the presence of contamination may lead to a serious infection. Both eyes may be involved, as the two reported cases show. Possible causes include mask friction on the open eye or other careless technics. Treatment includes local application of an antibiotic ointment and an eye pressure patch. In addition, a cycloplegic and mydriatic solution is instilled to prevent synechiae (in the presence of a secondary iridocyclitis) and to relieve the pain associated with spasm of the iris and ciliary muscle. Topical application of local anesthetics should be avoided, as they delay regeneration of corneal epithelium and may promote keratitis.

It has been used to characterize various ophthalmic disorders in adults. Currently there is no data describing orbital blood flow parameters in either normal children or in those with ophthalmic disease, such as the retinopathy of prematurity (ROP). We evaluated blood flow in the central retinal artery of preterm infants undergoing examination for ROP. We also investigated whether useful readings could be obtained on a consistent basis, and the reproducibility of differences in central retinal artery blood flow between subjects with and without ROP (including the influence of "plus" disease). We obtained hemodynamic readings in 43 of 46 eyes of preterm infants. 13 eyes had no signs of ROP; 18 had ROP (at least stage 1) without "plus" d...

The clinical manifestations consisted of swelling of the eyelids and necrosis of the lower eyelid regions, accompanied by high fever. Streptococcus pyogenes was isolated from the wound. The patient responded well to administration of intravenous amoxycillin/clavulanate and conservative local treatment. The infection resolved uneventfully. At 2-year follow-up, the cosmetic result was excellent. (Aesthetic Surg J 2005;25:270-272.)

In this retrospective study we analyzed the results of 198 eyes of 99 patients (randomly chosen) who underwent LASIK Zyoptix treatment and 198 eyes of 99 patients (randomly chosen) who underwent LASIK PlanoScan standard ablation treatment. Patients were followed for a period of 12 months after treatment. All surgeries were performed with the Bausch & Lomb Technolas 217z. Data on uncorrected (UCVA) and best spectacle-corrected (BSCVA) visual acuity, efficacy, predictability, stability and safety were analyzed. Mean preoperative spherical error in the Zyoptix group was -7.16 D (range= 0 to -16.50, SD = 3.21) and in the PS group -5.31 D (range= 0 to -16.50, SD=3.13). Mean preoperative cylinder was -1.30 D (range= -0.25 to 5.00, SD=0.99) and -1.17 D (range= -1 to -4.00, SD=0.85) respectively. Mean sph...
